Caption: Sagittal view of a vessel in the groin
Description: The vessel appears dilated and is filled with echogenic material suggestive of thrombus. The vessel was not compressible.
|
|
|
|
Caption: Multiple views of the vessel in the groin
Description: The same vessel is noted again. The echogenic material is again seen distending the vessel.
|
|
|
|
Caption: Sagittal and transverse views
Description: The same findings observed again. The vessel is the femoral vein. The femoral artery is seen adjacent to the vein in the transverse view.
|
|
|
|
Caption: Color Doppler of the femoral vein
Description: Some flow is noted in the thrombosed vein.
|
|
|
|
Caption: Spectral analysis of the flow in thrombosed vein
Description: The flow that was detected in the thrombosed vein shows an arterialized waveform.
|
|
|
|
Caption: Spectral analysis of the flow in thrombosed vein
Description: Multiple flow channels demonstrating arterialized flow pattern are detected in the thrombosed vein.
|

|
|
Caption: Spectral analysis of the flow in thrombosed vein
Description: The multiple flow channels showing arterialized flow are observed again in the thrombosed vein.
|
|
|
|
Caption: Spectral analysis of the flow in thrombosed vein
Description: A small channel of recanalized venous flow is noted.
|
|
|
|
Caption: Spectral analysis of the flow in thrombosed vein
Description: Similar finding is noted again with multiple areas of arterialized channels observed in the thrombosed vein. These findings are more in favor of a tumoral thrombus rather than a simple venous thrombosis.

Caption: Axial CT scan of the groin
Description: A large lobulated soft tissue mass is seen in close proximity to the right iliac crest. This was proven to be a sarcoma.
